Hoddle, Choe, Haviland receive $1.34 million for chlorpyrifos alternatives

From left, Mark Hoddle, Dong-Hwan Choe and David Haviland received CDFA grants for research on pest control alternatives to the banned pesticide chlorpyrifos.

The California Department of Pesticide Regulation has awarded $1.34 million in grants to UC ANR scientists for research on pest control alternatives to the banned pesticide chlorpyrifos.

"Finding less-toxic alternatives to pesticides like chlorpyrifos, and promoting their adoption and implementation throughout California, is a priority, and our grant programs play a vital role in reaching those goals," DPR Director Val Dolcini said.

The grants, awarded through DPR's Research Grants Program, will go to the following researchers:

  • Mark Hoddle, UC Cooperative Extension entomology specialist, UC Riverside, "Taking Chlorpyrifos out of Citrus: Maximizing IPM of Argentine Ant and Sap Sucking Pests with Biodegradable Hydrogels, Infra-Red Sensors and Cover Crops." ($500,000)
  • Dong-Hwan Choe, UC Cooperative Extension urban entomology specialist, UC Riverside, "A sustainable boric acid liquid bait delivery system (as alternative to chlorpyrifos sprays) for the management of pest ants in agricultural settings." ($340,467)
  • David Haviland, UC Cooperative Extension IPM advisor for Kern County, "Hydrogel baiting systems for sugar-feeding ants in California grapes and citrus." ($500,000)

"These researchers are at the cutting edge of their fields and I'm really pleased that DPR can support their efforts," said Dolcini.

 

New DPR grants enable research into alternatives to the banned pesticide for citrus, grapes and other crops.

Full descriptions of each research project are available on DPR's website.

Funding for these grants came from a one-time $2.1 million General Fund allocation to DPR for research projects that advance safer, more-sustainable pest management alternatives to chlorpyrifos. DPR previously funded three research grants for alternatives to chlorpyrifos research.

Following California's historic decision to end use of the pesticide chlorpyrifos in 2019, DPR and the California Department of Food and Agriculture (CDFA) convened the Alternatives to Chlorpyrifos Work Group to evaluate potential alternatives. The work group's report outlines actions that can further support agriculture and the health of local communities, farmworkers and the environment.

Choe, Dara and IPM team honored by Pacific Branch of ESA

Dong-Hwan Choe
UC ANR scientists Dong-Hwan Choe, Surendra Dara, David Haviland and Jhalendra Rijal received awards for their exemplary work from the Pacific Branch of the Entomological Society of America. The PBESA presented its annual awards on April 20, at a virtual ceremony due to the coronavirus pandemic.

Choe, UCCE specialist in the UC Riverside Department of Entomology, won the Medical, Urban, and Veterinary Entomology Award.

“Since joining the faculty at UC Riverside in 2011, [Choe] has developed an outstanding research and extension program dealing with the major urban structural pests and related issues in the western United States,” wrote Mike Rust, UC Riverside entomology professor, in his nomination letter.

His research includes exploiting the role of semiochemicals and behavior to control social insects and developing novel ant baits.

“Dr. Choe has been at the forefront of developing hydrogels as carriers of baits to control ants and yellowjackets. Developing cost-effective and environmentally safe delivery strategies has always been a major problem facing the use of ant baits in agriculture and urban setting. His pioneering biodegradable alginate beads promise to be a major advancement,” Rust wrote.

Surendra Dara
Choe also participates in workshops for agricultural pest control advisers, UC Master Gardeners and urban pest control operators.

Dara, UC Cooperative Extension entomology and biologicals advisor for San Luis Obispo and Ventura counties, won the Award for Excellence in Integrated Pest Management.

This annual award recognizes individuals who made outstanding contributions in research and outreach in the area of IPM. Dara's new IPM model has been well-received and its impact has been documented in a UC Delivers story. Dara is the first UC ANR scientist to receive this award and fourth from UC since the Pacific Branch began offering awards in this category in 2009.

The UC IPM Almond Pest Management Alliance Team won the Entomology Team Work Award. The team consists of UC IPM advisors David Haviland and Jhalendra Rijal, former UCCE advisor Emily Symmes, UCCE Kern County staff research associate Stephanie Rill, industry researcher Bradly Higbee of Trécé, USDA scientist Charles Burkes and Bob Curtis of the Almond Board of California.

The team encouraged the adoption of mating disruption for managing navel orangeworm, a major pest in almond orchards, especially in the San Joaquin Valley. After they began demonstrating that mating disruption proved to be an economical pest control method in orchards, they saw a rapid rise in growers adopting the technology. Based on a survey of pest control advisers and growers conducted in the early 2019, the anticipated use of navel orangeworm mating disruption for the 2019 season in San Joaquin Valley was 32%, as opposed to the 7% adoption in 2017. Kern County data showed a 26% countywide increase in the adoption of mating disruption from 2017-2018.

UC Research to Policy Conference puts science into action

Jason Delborne described the roles of a scientist in policy as outlined in Roger A. Pielke, Jr.'s book "The Honest Broker": pure scientist, issue advocate, science arbiter and honest broker.
A diverse group of UC scientists working on agricultural, natural resources and food issues came together at the First Research to Policy Conference to explore how to use research to effectively engage in public policy. The event, hosted by UC Agriculture and Natural Resources and UC Davis College of Agricultural and Environmental Sciences, was held on the UC Davis campus on Oct. 12-13.

“We focused on fostering a good dialogue and facilitating co-learning among attendees,” said event co-chair Leslie Roche, assistant UC Cooperative Extension specialist in rangeland management. “We hosted university faculty, statewide CE specialists and academics, and county-based CE advisors—as well as local policymakers and leaders from non-governmental organizations and statewide programs.”

UC researchers who have successfully engaged in the public policy arena provided numerous models of linking research and policy. There were five key take-aways for scientists:

-          Honest broker role – Present policymakers with various policy options, based on sound research. Have a clear understanding of the science behind your messaging. Use qualitative data to tell the story of the hard quantitative data.

-          Active engagement – Be part of informational and oversight hearings. Empower communities to take action and foster community engagement.

-          Build coalitions – Collaboration is imperative. Develop unexpected allies and foster long-term relationships, realizing it may take some time to bear fruit.

-          Disseminate information – Share your data in user-friendly formats. Target local community, Legislature and state agencies to inform policies. Get your science into trainings and continuing education programs. Leverage your coalition to expand the circulation of your research results.

-          Target messages – Develop a strong, concise message to deliver your research. Use an emotional connection – “Old-growth oak woodlands” versus “oak woodland.”

Throughout the conference, speakers highlighted the multiple levels of engagement for researchers in the policy arena, with different roles matching different needs – some take a center stage, while others play imperative behind-the-scenes roles.

Keynote speaker Jason Delborne, associate professor of science, policy and society at North Carolina State University, encouraged engaging the public. “Science is a social process,” he said, noting that community and public engagement is often key to successfully applying research to policy. Delborne also touched on the tension between expertise and democracy, commenting that we can't always resolve it and often we have to learn to live with this tension.

From left, Mindy Romero, Lorrene Ritchie, Thomas Harter, David Lewis and Yana Valachovic, shared what they have learned from engaging in policy.

A diverse set of researchers shared their perspectives from experiences in engaging in policy. The panel included Thomas Harter, Robert M. Hagan Endowed Chair in Water Management and Policy and UCCE specialist in the Department of Land, Air, and Water Resources at UC Davis; Lorrene Ritchie, director of the UC ANR Nutrition Policy Institute; Mindy Romero, founder and director of California Civic Engagement Project at UC Davis Center for Regional Change; and Yana Valachovic, UCCE forest advisor and county director in Humboldt and Del Norte counties. They discussed the importance of building strong science-based programs, actively engaging local communities and building coalitions of support.

From left, Amrith Gunasekara, Tina Cannon Leahy, Anne Megaro, Rebecca Newhouse and Juliet Sims described how they use research to shape policy.

Guests from both government and non-government organizations who use research to shape policy shared their perspectives on translating science to decision-making.

“Science is the foundation for developing programs,” said Amrith Gunasekara, science advisor for the California Department of Food and Agriculture.

Tina Cannon Leahy, attorney with the State Water Resources Control Board, noted that policymakers and decision-makers are often looking for a clear, “black-and-white” answer, while for scientists, there is “no answer,” but rather information.

Anne Megaro, consultant to the California Senate Committee on Agriculture, and Rebecca Newhouse, consultant to the California Senate Environmental Quality Committee, both emphasized the importance of making sure science is accessible and digestible.

Juliet Sims of the Prevention Institute explained how her organization uses both published scholarly literature and community stories to effectively inform its advocacy platform.

Keynote speaker Rachel Morello-Frosch, associate professor in the Department of Environmental Science, Policy and Management at UC Berkeley, introduced the concept of moving from “translational research” to “transformational research,” a shift that requires deep community engagement in meaningful ways to effect policy change.

During a breakout session, participants discuss current research that has policy implications.

In the afternoon, four breakout sessions were offered: “Policy structures and opportunities for engagement” with Robert Waste, “Relational approaches to science communication and engagement” with Faith Kearns, “Putting it into practice–UC ANR case studies” with Dave Campbell, Clare Gupta and Lucas Frerichs, and “Navigating policy engagement: Education vs advocacy,” with Adrian Lopez and Kit Batten. These training modules helped participants build technical skills and analytical frameworks for successful policy engagement.

The Research to Policy Conference was a forum to exchange ideas and share perspectives, continuing to bridge the gap between science and policy communities. It challenged attendees to be open to new ways of thinking, shared innovative outreach methods and showcased how research can have an impact in the policy arena.

“The event brought cross-fertilization and co-learning between disciplines – nutrition, forest management, water quality – and there were common themes that resonated for all participants,” said event co-chair Gupta, assistant UCCE specialist in public policy and translational research.

VP Glenda Humiston wrapped up the policy conference by saying, "Good science is vital for good policy. It's great to see UC folks enhancing these skills to bring science together with policy."

Pourreza wins international prize for HLB detection

Ali Pourreza

Newly appointed UC Cooperative Extension agricultural engineering advisor Alireza Pourreza has been awarded the 2016 Giuseppe Pellizzi Prize by the Club of Bologna, an honor presented every other year to the best doctoral dissertations focused on agricultural machinery and mechanization. The Club of Bologna is a world taskforce on strategies for the development of agricultural mechanization.

Pourreza, who earned his Ph.D. at the University of Florida in 2014, worked on early detection of Huanglongbing disease of citrus. Huanglongbing, an incurable disease that is spread by Asian citrus psyllid, has seriously impacted citrus production in Florida. The disease has been found in commercial and residential sites in all counties with commercial citrus.

Early detection allows growers to remove infected trees before the disease can spread to healthy trees. Currently HLB infection is confirmed when leaves with yellowing blotches are submitted for PCR testing, which is expensive and time-consuming. However, the yellowing can be also symptomatic of other conditions, such as nutrient deficiency.

"We discovered we could see the symptoms of Huanglongbing using a camera, a set of cross-polarizers and narrowband lighting before it is visible to the human eye," said Pourreza, who is based at the UC Kearney Agricultural Research and Extension Center in Parlier.

He said the yellow blotches on HLB-infected leaves are caused by starch accumulation.

"If we could detect abnormal levels of starch in the leaf, we could tell it is affected with HLB," Pourreza said. "Starch showed the ability to rotate the polarization plane of light. We used this optical characteristic to develop the sensing methodology."

Pourreza said the team has patented the technique and is working on developing a commercial product. He is seeking funding to continue the research in California, where, to date, HLB has only been detected in isolated Los Angeles neighborhoods. Asian citrus psyllid is found in important California commercial citrus production regions from the Mexican border to as far north as Placer County.

4-H Youth Development team wins national diversity award

4-H Youth Development advisors Dorina Espinoza, Russell Hill, Fe Moncloa and Keith Nathaniel and 4-H associate director Shannon Horrillo have won the National Extension Diversity Award for systematically enhancing the intercultural competency of 4-H personnel and others in California.

The award, given by USDA National Institute of Food and Agriculture (NIFA), Cooperative Extension System and the Association of Public and Land-grant Universities (APLU), honors the team for creating and using Intercultural Development Inventory© to shift organizational culture. This shift includes mutual respect, acceptance, teamwork and productivity among diverse people.

To meet the needs of a culturally and ethnically diverse youth population in California, they created a professional-development intervention for 4-H academics and staff. The Intercultural Development Inventory© is a cross-culturally generalizable, valid and reliable assessment of intercultural competence. Calling themselves the Intercultural Development Inventory Qualified Administrators, they applied the strategy over three years, providing 176 hours of intercultural communication feedback sessions, learning communities and regional conferences to enhance the intercultural competence of 65 4-H personnel.

Evaluations demonstrated that after the intervention UC 4-H Youth Development Program personnel had acquired skills and characteristics to become more culturally competent. The program has moved from focusing on similarities across diverse people that can mask deeper recognition of cultural differences to recognizing the complexity of dimensions of diversity.

The action plan and resulting positive change provides the potential to improve hiring and professional development nationwide by replication in other states. A summary of California's IDI professional development activities can be found in the National 4-H Latino Youth Outreach: Best Practices Toolkit, Professional Development.

The National Extension Diversity Award will be presented on Nov. 13 at the 129th APLU Annual Meeting in Austin, Texas.
